What the Features Do

Here are brief descriptions of the features which you can use with an ISDN 8520Tvoice/data terminal connected to a DEFINITY Communications System Generic 1 orGeneric 3. The following descriptions include what each one does and how you mightwant to use it.

The features in this section are divided into three main categories: Fixed (Button)Features, Display and Softkey Features, and Switch Features. Onlyprocedures for the last type, Switch Features, are provided in this guide.

● Fixed (Button) Features— These voice/data terminal features, such asConference, Drop, Hold, and Transfer, have been assigned to particular buttonson the voice/data terminal when it is built at the factory. Thus, when you receivethe voice/data terminal, you can use these features immediately. Descriptions ofthese features appear below and on the next page. For directions on using thesefeatures, see the DEFINITY Communications System ISDN 8520T Voice/DataTerminal User’s Manual, 555-021-758.

● Display and Softkey Features— The features in this category are accessedwith the 10 softkeys (the unlabeled buttons on either side of the display), the fourdisplay control buttons ( [ Menu ], [ Dir ], [ ← ← Prev ] , [ Next →→ ] ), and the 7-lineby 24-character display. These features include a personal Directory, a Call Logof the most recent answered and unanswered calls, and the Self-Test feature.This section provides descriptions of the Display and Softkey features. Forprocedures for using these features, see the AT&T DEFINITY® CommunicationsSystem ISDN 8520T Voice/Data Terminal User’s Manual (555-021-758).

● Switch Features— You can use these features only with a DEFINITY Generic 1or Generic 3, and if these features have been assigned to your voice/dataterminal. Check with your system manager to see which of these features youcan use.

Fixed (Button) Features

Abbreviated Dialing Allows you to store selected telephone numbers for quick andeasy dialing. Each number can be a complete or partial telephone number, anextension number, or a trunk or feature code. There are four possible types oflists—personal, group, system, and enhanced—and you can have a total of three outof the four possible lists (see your system manager for details). Numbers on apersonal list are programmable by you; numbers on all other lists are programmableonly by the system manager. Use as a timesaver for dialing frequently called,lengthy, or emergency numbers.

Automatic Callback Sends you a special 3-burst ringing tone indicating that apreviously busy or unanswered extension is now available. Use to avoid constantredialing when you wish to speak to someone who is frequently busy on the voiceterminal or in and out of the office. Note: This feature can be used only forextensions, not outside numbers.

Call Forwarding All Calls Temporarily forwards all your calls to another extensionor to an outside number, depending on your system. Use when you will be awayfrom your voice/data terminal and you want your calls to be forwarded to a voiceterminal of your choice.

Call Park Puts a call on hold at your voice/data terminal for retrieval at anyextension. Use when you need to go elsewhere to get information during a call, orwhenever you wish to complete a call from a different location. Also, if the callreceived is for someone else, use it to hold the call until the called party can answerit from the nearest available voice terminal.

Use when you wish to handle a call for a groupmember who is absent or otherwise unable to answer. Note: You can only use thisfeature if you and the called party have been assigned to the same pickup group byyour system manager.

Leave Word Calling Leaves a message for another extension to call you back. Thecalled party will be able to dial message service (for example, attendant, AUDIX,covering user, etc.) to retrieve a short, standard message which gives your name andextension, the date and time you called, and the number of times you called. Useany time you wish to have someone call you back; it will help cut down on repeatedcall attempts.

Priority Calling Allows you to call another extension with a distinctive 3-burst ringto indicate that your call requires immediate attention. Use when you haveimportant or timely information for someone.
